A high-pressure pump takes water in at $70^{\circ} \mathrm{F}, 1 \mathrm{~atm}$, through a $1 \mathrm{in}$. ID suction line and discharges it at 1000 psig through a 1/8 in. ID line. The pump is driven by a $20 \mathrm{hp}$ motor and is $65 %$ efficient. If the flow rate is $500 \mathrm{~g} / \mathrm{s}$ and the temperature of the discharge is $73^{\circ} \mathrm{F}$, how much heat is transferred between the pump casing and the water per pound of water? Does the heat go into or out of the water?
